Patented Aug. 31, 1937 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to a paper dispensing device, and especially to a combination holder and cut-off blade for use in connection with rolls of paper from which the paper is torn ofi in sheets of varying length.

The object of the present invention is to provide a combination paper roll holder and cut-off blade which is particularly intended for domestic or household usefor instance, in the average 10 kitchen, to supply paper toweling, waxed paper and like products; to provide a device of this character which may be made throughout of stamped sheet metal, and of parts that may be quickly and readily assembled; to provide a base plate for the support of a paper roll and a cutoff blade; and further, to provide a novel connection between the cut-off blade and the base plate whereby the two may be readily connected and'pivotal movement of the blade with relation to the plate and the roll may be had.

The device is shown by way of illustration in the accompanying drawings in which Fig. l is a perspective view of the paper holder and the cut-01f blade;

Fig. 2 is a cross section taken on line II-II,

Fig. 1;

Fig. 3 is a similar section showing the cut-off blade in raised position;

Fig. 4 is a perspective view showing the rear side of the wall plate; and

Fig. 5 is a perspective view of the cut-off blade. Referring to the drawings in detail, and particularly to Fig. 1, A indicates a base or wall plate to opposite ends of which are secured supporting or bracket arms 4.

Disposed between the arms and supported thereby is a paper roll I, and engageable with the roll is a cut-off blade 2 which is provided. with a tearing or cutting edge 3.

Serial No. 123,376, filed February 1, 1937.

The

construction of the cut-off blade and the manner in which it is supported and connected with the base plate is important, as it forms the subject matter of this application.

The blade is constructed of a single piece of sheet metal which extends substantially from end to end on the roll.

It is bent to arcuate form as shown, and the outer edge is in turn bent to form a cutting or tearing edge 3.

The

opposite edge of the blade is provided with three lugs (see particularly Fig. 5) which are indicated at 7, 8 and 9. All of the lugs are bent substantially at right angles to the blade, and the lugs 8 and 9 are slotted to form retaining or interlocking tongues i2 and 13. The lugs l, 8 and 9 serve the function of a hinge or pivotal connection between the cut-off blade and the base plate A as they extend through slots la, 8a and 90., forming the plate, and are free to swing therein. The tongues i2 and I3 serve the function of retaining the lugs against endwise removal from the slots, while lug I, which cooperates with the tongues, secures the lugs against longitudinal movement in the slots as will hereinafter appear.

As actually constructed, all parts are formed of punched or pressed sheet metal to give light weight and strength. The base plate itself is flanged as indicated at A to give the proper stiffness and rigidity, and to provide a space on the rear side thereof for a spring I0 which will here inafter be described.

When assembling of the parts is taking place, the brackets 4 will first be applied and then the cut-off blade. This is accomplished by first inserting the lugs 9 and 8 in the slots 9a and 8a. The blade is then moved longitudinally in the direction of the arrow at until the tongues 12 and I3 assume the interlocking position shown in Fig. 4. At this point lug 1 will register with and enter the slot la, and when it enters it will dog or look the blade against reverse longitudinal movement, while the tongues I2 and 13 will retain the lugs against endwise movement or, in other words, from being pulled out of the slots. It should be understood that it will be necessary to slightly spring the blade when lugs 9 and 8 are first introduced into their slots and move longitudinally therein as lug '1 cannot enter its slot la until lugs 8 and 9 assume their final position.

After the lugs on the cut-off blade have been entered and interlocked as described, a fiat spring H3 is riveted, welded, or otherwise secured to the rear side of the base plate. This spring engages the lug 8 and exerts sufficient pressure therein to maintain the cutting or tearing edge 3 in firm contact with the surface of the paper roll, said spring also serving to hold the cut-off blade in the raised position shown in Fig. 3 when the paper roll is to be inserted or removed.

The entire structure and mechanism disclosed is exceedingly simple and substantial in construction, easy to assemble, install and operate. It may be enameled or finished in any color desired,

and provides a fixture which not only possesses great utility, but is also ornamental wherever placed. It is sanitary because it is easily cleaned, and dust is excluded to a great extent as the cut-off blade substantially covers the paper roll, or, in other words, forms a housing thereover.

While this and other features of the present invention have been more or less specifically described and illustrated, I wish it understood that changes may be resorted to within the scope of the appended claims, and that the materials and finish of the several parts employed may be such as the manufacturer may dictate or varying conditions may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. In a roll paper dispenser of the character described, a base plate, means on the plate for supporting a roll of paper, a cut-off blade overlying the paper roll and having a cutting edge in contact with the surface of the roll, a plurality of lugs on the opposite edge of the cut-off blade and extending through slots formed in the base plate to provide a hinged connection between the base plate and the cut-off blade, and a spring fixed to the base plate and engageable with one of the lugs to maintain the cutting edge of the cut-off blade in firm contact with the surface of the paper roll.

2. In a roll paper dispenser of the character described, a base plate, means on the plate for supporting a roll of paper, a cut-off blade extending from end to end of the roll, said blade being arcuate in cross-section and overlying the roll to form a cover therefor, a cutter formed on one edge of the blade, a plurality of lugs on the opposite edge of the cut-elf blade and extending through slots formed in the base plate to provide a hinged connection between the base plate and the cut-off blade, and a spring fixed to the base plate and engageable with one of the lugs to maintain the cutting edge on the cut-off blade in firm contact with the surface of the paper roll.

3. In a roll paper dispenser of the character described, a base plate, means on the plate for supporting a roll of paper, a cut-off blade extending from end to end of the roll, said blade being arcuate in cross-section and overlying the roll to form a cutter therefor, a cutter formed on one edge of the blade, a plurality of lugs formed on the opposite edge of the blade and extending through slots formed in the base plate to provide a hinged connection between the base plate and the cut-off blade, means securing the lugs against endwise and longitudinal movement in the slots, and a spring fixed to the base plate and engageable with one of the lugs to maintain the cutting edge of the cut-off blade in firm contact with the surface of the paper roll.

4. In a roll paper dispenser of the character described, a base plate, means on the plate for supporting a roll of paper, a cut-off blade extending from end to end of the roll, said blade being arcuate in cross-section and overlying the roll to form a cutter therefor, a cutter formed on one edge of the blade, a plurality of lugs formed on the opposite edge of the blade and extending through slots formed in the base plate to provide a hinged connection between the base plate I and the cut-off blade, a retaining tongue on one of the lugs securing the lugs against endwise removal from the slots, other means securing the lugs against longitudinal movement in the slots, and a spring fixed to the base plate and engageable with one of the lugs to maintain the cutting edge of the cut-off blade in firm contact with the surface of the paper roll.
